Circular Motion10111051011304Circular MotionCentripetal ForceWhenever a moving object turns, its velocity changes direction. Since acceleration is a measure of the rate of change of velocity, an object that turns is accelerating. This kind of acceleration, called centripetal or radial acceleration, is related to v, the speed, and r, the radius of the curvature of the turn, by ac = v2/…Next Chapter >< Previous Chapter
